Improvement in buckles

Letters Patent N 100,063, (lated March 22, 1870.

IMPROVEMENT IN BUCKLES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, Mosns ADAMS, ol' Chilmark, in `Dukes county, Stateof Massachusetts, have invented a newand useful. Improvement in Buckles;and I do hereby declare that the following is a full, clear, and exactdescription ot the construction and operation ofthe same, referencebeing had to the annexed drawings making a part of this specification,in which- Figure 1 is a perspective view. l Letter A is on the fra-me.

Letter B is on the upper part of the lever.

Letter O is on the trace or material for which the buckleis used.

Letter 1) is on a frame for the material to be rove through, in order totake up and letlout.

Letter E is on the pawl or under part of the lever l Letter F is on thecross-bar of the buckle.

Figure 2 is a longitudinal. elevation.v

.A denotes the frame. B, the lever.

O, the flexible material.

D, the frame, ring, or staple.

E, pawl or under part of the lever.

F, the crossAba-r. v

Figure 3 is a transverse section, showing the act-ion of lever B,pressing the material on the cross-bar F.

The other letters denote the same parts as in fig. 1 and lig. 2.

The principle ot' constructing my improvement on the buckle is simply tomake the frame oblong, with a cross-bar near the end toward the lever.

The pawl or under part of the lever, asl seen in g. 2, letter E, shouldcome as far short of the cross-bar as the thickness of the material forwhich it isintended.

When made for traces, the end ot' the lever should be open, to receivethe end of the trace, so as to fasten by rivets.

To use the buckle for traces, reeve the forward end under the lever B,over cross-bar F, under the forward end of the buckle A, through stapleou the llames, as seen at letter D, thence back' under the for- Ward endof 'the'buckle, and fastened to the lever B, as seen in fig. 1.

The buckle is adapted to all purposes for taking up and letting out,without letting go. It is a sliding and self-fastening buckle; holds hylever power. The strain draws the lever down on the cross-bar, by whichmeans the buckle holds, wherever placed.

What I claim as my invention, and desire to secure by Letters Patent,isy The combination of the lever B, cross-bar F, and frame A, with thepawl E, all constructed and operating substantially as described.

MOSES ADAMS.
